MACHINE FOR DYEING, WASHING, SCOUBING, SIZING, BLEACI-IING', AND MERCERIZING YARN IN HANK FORM.

Application filed April 11,

To all whom it may concern:

Be it known that we, Josnrrr' SPENCER Loan and SAM SrnNonn LORD, both subjects of the King of Great Britain, residing at Manchester, in the county of Lancaster, England, have invented certain useful Improvements in Machines for Dyeing, l/Vashing, Scouring, Sizing,-Bleaching, and Mercerizing Yarn in Hank Form, of which the following is a specification.

This invention relates to that type of machines for dyeing, washing, scouring, sizing, bleaching and mercerizing yarn in hank form, in which the hanks are placed on reels or rollers and thereby rotated through the liquor used.

This invention has for its object the construction of a machine for carrying out the said, operations, which dispenses with a great deal of labor hitherto necessary in the said type of machines, saves a considerable amount of liquor and turns out more and better work than hitherto has been the case.

A machine constructed in accordance with this invention comprises chiefly a horizontally rotating central shaft having secured thereto at one or both ends a roller, one or more sets or heads of radial arms loosely mounted on the said shaft adjacent to the said roller orrollers and'a pair of horizontally rotary members carried by each of the said radial arms adapted to receive the hanks to be treated, the said roller or rollc ers on the said central shaft being adapted to rotate the inner of the said rotary members either by frictional contact or positively, by. gearing up said central shaft with the rollers, to press the liquor through the hanks and out'of them and also to intermittently rotate the saidsets or heads of radial arms bycontact with the inner of the said rotary members.

The machine further comprises a liquor tank located below each set or head of radial arms, into the liquor of which the hanks on the said rotary members are passed and through which they are rotated.

The machine also comprises means for bringing the inner of the said hank rotating members automatically in and out of contact with the said central roller or rollers to permit of placing the hank onto the said rotary members for treatment and removing same when treated.

We attain this object by the mechanism.

Specification of Letters Patent.

1919. Serial No. 289,459.

illustrated in the accompanying two sheets of drawings, in which Figure 1 is an end view; Fig. 2, a sectional end view; Fig. 3, a detached view partly in section on line 33 of Fig. 4; Fig. 4;, a side View partly in section; and'Fig. 5, a plan.

Similar letters refer to similar parts throughout the several views.

Referring to the figures generally the frame of the machine is composed of four sides a, a and Z), Z), suitably bolted together and with liquor tank 0 at each end. On the said frame sides a horizontal shaft d is centrally mounted in suitable bearings e and continuously rotated, say by means of spur gearing f, g, pulley 7L and strap.

e'ferring to Figs. 1-5, on each end of the horizontal shaft (Z is secured a central roller 2' and between the same is loosely mounted a sleeve A: to each end of which is secured a set or head of radial arms Z, say forexample, each comprising four arms.

The outer end of each of the said arms is furnished with a radially adjustable shaft n on which is mounted a reel m. Each of the arms Z has near its inner end a radial slot 0 through which extends a shaft p having at each end loosely mounted a rotating roller Q', adapted to run in frictional contact with the central rollers 2'.

Each shaft 39 is mounted in two bearings located adjacent to the inner sides of the radial arms Z which bearings are suspended from the latter by means of strong coiled springs s. a

On the frame side I) is secured an annular bracket 5 concentric with the horizontal central shaft (Z and having at the feeding side of the machine,,internally a cam cavity a forminga dwell. 7

On each end of the roller shaft 22 is adapted to rotate loosely a collar o having at each side a flange adapted to fit against the respective sides of the annular bracket 2?.

Each shaft p has secured thereto a collar to bearing against the inner side of the said collars 4) whereby the shafts p are retained longitudinally in position.

The said annular brackets t are internally formed with anannular groove 01:, in which is secured a semi-circular flat spring the free end of which is placed under the influence of a coiled spring 2 rendered adjustable by means of a screw 2 located in an arched bracket 3 secured to the annular bracket t.

By means of the said spring device, the pressure upon the rollers q and consequentl upon the hanks a may be varied as required to more or less impregnate the hanks with and press out the superfluous liquor.

Each end of the shafts 12 carries a collar 6, 6, adapted to come into contact with bowsprings 5, 5, secured to the frame sides a, a, while the hank rotates through the liquor and thereby press the hank against the central rollers i to squeeze the liquor through the hanks.

Below the path of the roller shafts 1) a weighted lever 7 is secured to a shaft 8, see

Figs. 2 and 3, which has two upwardly projecting catches 9. adapted to engage behind the shafts p, as they reach the bottom position and thereby lock the radial arms Z in position while the hanks are removed and replaced. After having replaced the hanks the lever 7 is lowered by hand or automatic meausand the radial arms Z allowedto rotate again. The radial arm Zmay be fur-* nished with two guide rods 10 adapted to keepithe hanks l laterally in position on the reels mand rollers In lieuof rotating the rollers Q from the central rollers z' frictionally, in case of hanks of thick yarn or thick hanks, they may be positively driven by means of spur wheels secured to the inner ends of the rollersg and to the drivingshaft cZ adjacent to the inner endof the central rollers 71.

Thecycle of operation of the machine described is as follows r In the position of the radial arms Z shown in the drawing, the roller shafts 2) having enteredthe cam cavities a, the rollers g thereon are out of contact withthe central rollers 71 and thus at rest, and the lever catches 9 having engaged behind the roller shaft p'situated below the central. rollers c, the radial'arms Z remain locked in position, asshown more particularly in l, 2, 3 and 4, while the other rollers q are being rotated frictionally by said central rollers z or positively from said central shaft. After having placed a number ofhanks on the rollers g and respective reels m, then at rest, the radial arms Z are unlocked by means of the lever 7 and the said arms then intermittently rotated by the contactof said central rollers with said inner rollers q, the latter remaining stationary on their shafts and consequently the hanks at rest while the intermittent rotation of said arms takes place.

.In the meantime the shaft p located in the cam cavities u is caused to leave same and traveling along the interior of the bracket t, the rollers g and the hanks 4: are brought into contact with the central rollers z and thereby rotated, while at the same time the hanks 4 are lowered into the liquor in the tanks 0. By the time the hanks arrive be low the central rollers 'Z, the nextfollowing roller shaft p is timed to enter the cavities u to receive together with the respective reel m and roller 9 another number of hanks l.

The operation so far described repeats itself during each following intermittent rotation of the radial arms Z.

' lVhile the first number of hanks 41: rotates in the liquor, owing to the pressure exerted thereon by the rollers 9, they are thoroughly and evenly impregnated by the liquor.

On the next intermittent rotation of the radial arms Z the first number of hanks is brought from the vertical, into a horizontal position opposite the feeding side of the ma chine and the second number of hanks will be lowered into the liquor.

iVhile the first number of hanks is traveling from the vertical position below the ers g passing the-hanks against th central rollers i, and when arriving'at tieir initial horizontal position, are ready for removal from the machine.

By the machine described, the treatment of the hanks is rendered continuous, uniform and rapid, because while one batch of hanks is placed on or removed from the rollers and reels, another batch undergoes treatment 1n the liquor and a further batch has pressed out of it the superfluous liquor.

It will be obvious that the machine described may be built to have more than two sets or heads of radial arms, and that one person can attend to a number of machines, also that when having more than four radial arms, say six, the said annular brackets may have each a second dwell and thus permit of placing the hanks on to the said rotary member and removing same therefrom simultaneously at both sides of the machine.

We claim a 1. A machine for dyeing, washing, scouring, sizing, bleaching and mercerizing yarn, comprising a frame, a driving shaft mounted thereon, a central roller secured to, and a set of intermittently rotatable radial arms mounted on said shaft near each end thereof, a pair of horizontally projecting rotary yarn carrying members on each radial arm, the inner members being in frictional contact with said central rollers and a liquid tank located below each set of said arms and yarn carrying members, for the purpose specified.
